<Java多线程编程核心技术>讲解得太细致啦
一个synchronized关键字，能讲一百多页，搞出几十个小举例。 我是服了！ 但真的一路演练一下， 对这个关键的应用场景还是了解了很多的。 package test; public class Service { private boolean isContinueRun = true; public void runMethod() { String anyString = new String(); while (isContinueRun == true) { synchronized (anyString){ } } System.out.println("have stopped."); } public void stopMethod() { isContinueRun = false; } } package test; public class ThreadA extends Thread { private Service service; public ThreadA(Service service) { super(); this.service = service; } @Override public void run() { service.runMethod(); } } package test; public class ThreadB extends Thread { private Service service; public ThreadB(Service service) { super(); this.service = service; } @Override public void run() { service.stopMethod(); } } package test; public class Run { public static void main(String[] args) throws InterruptedException { // TODO Auto-generated method stub try { Service service = new Service(); ThreadA a = new ThreadA(service); a.start(); Thread.sleep(1000L); ThreadB b = new ThreadB(service); b.start(); System.out.println("have set stop order."); } catch (InterruptedException e) { e.printStackTrace(); } } }
